完整自主浏览

用自然语言驱动的 AI 浏览器自动化。告诉它要做什么，看着它替你浏览。

为现代 Web 而生

由领先的 AI 模型驱动，提供智能浏览器自动化所需的一切。

Direct API Execution

Beyond clicking. FSB can call an app's own authenticated API through your logged-in session. Faster and more reliable than DOM automation, with DOM as the automatic fallback. Inspired by OpenTabs.

60 Browser Actions

Click, type, scroll, drag-and-drop, canvas drawing, CDP mouse control, multi-tab management, and more. 53 DOM actions plus 7 through the Chrome DevTools Protocol.

Reactive Triggers

Watch any element and get notified the instant a value changes, crosses a threshold, or matches a pattern.

智能 DOM 分析

增量 DOM 差分、多策略选择器以及元素识别，让自动化更可靠。

Autopilot

Rebuilt on the Lattice SDK, long runs survive Chrome's MV3 shutdowns and finish. Up to 64 concurrent tabs, plus real file uploads from disk.

可视化反馈

Glow borders, pulsing element highlights, and a floating progress overlay show exactly what FSB is doing.

站点情报

130+ built-in site guides across 17 categories, from commerce to coding.

MCP 集成

Use FSB as an MCP server from Claude Code, Codex, Cursor, OpenClaw, or any MCP client. 66 tools, with browser automation straight from your IDE.

远程控制台

Monitor and control FSB from any device. QR-code pairing, a live DOM preview powered by PhantomStream, now with media mirroring, and real-time task execution.

记忆与学习

FSB 跨站点记住导航模式。语义、情景、过程性三类记忆让自动化随着时间越来越聪明。

比它们都强。无需视觉。

Project Mariner、Claude Computer Use、OpenAI Operator、OpenClaw。它们都依靠视觉理解页面。FSB 读取真实的 DOM。无需视觉，更快、更便宜、更准确。

与它们协同工作

FSB 不只是竞争，更是互补。通过它的 MCP 服务器，Claude Code、Codex、Cursor、Windsurf 以及任何兼容 MCP 的智能体都能把 FSB 用作浏览器自动化层。把任意 AI 的智能与 FSB DOM 引擎的精度结合在一起。

Native API handlers

It clicks when it must. It calls APIs when it can.

FSB no longer has to drive a UI for everything. For supported apps it talks straight to the app's own authenticated API through your logged-in session, far faster and more reliable than DOM automation, and falls back to clicking automatically when no API exists.
